Just so you guys know, I just picked up my ATS from Magnaflow. They used my car to mock up a cat-back system. Should be setting pricing soon if not already.

Now I just need a CAI. Who's got one that performs?

You can't get water from a stone either. The HHR is a V8 and you're comparing it to a 4 cylinder. When was the last time a 4 cylinder didn't sound like a vacuum cleaner?

Lol @ v8 hhr.

I wonder how their catback system attached to the car. Since there are no flanges or anything to do a bolt on install. After the cat it's all one pipe with welds.

BTW here is my setup for your comparison reasons. Also magnaflow. Bear in mind I'm recording with a phone camera and not the best mic.

It's all personal preference on sound. I'll admit that it was quieter than I expected but noticed that it has progressively gotten louder over time. Not sure why. For me if I wanted something obnoxiously loud I would have bought an STI instead. So this works for me.

The exhaust is configured very similar to a G35 exhaust. One muffler, two separate chambers, two tailpipes. I'll post pics later.

At the end of the day we are driving a Cadillac so it is a good thing it does not sound like a ricey Honda. I just expected a little more growl/throatier sound because it sounds a bit raspy right now.

u have to cut the stock exhaust even if u buy this system from magnaflow. which is unfortunate. wish GM had made a flange right after the cat.

I've delt with enough sezied studs, nuts and flanges to be thankful all that's required is a 10 minuite hacksaw job.

In the long-run, if you ever want to go back, a pair of joint clamps will let you put the stock exhaust on without having to re-weld anyway. I just did so with my V.

lulz at external wastegate...I know alllll about it.

You should see my 2JZ RX-7. I have a straight-up open dump-pipe coming right off the 45mm Turbosmart external wastegate. :P

I think a full 2.5" or even 3" exhaust with high-flow cat and resonator will really give the ATS 2.0T the aggressive exhaust note it needs without being TOO much.

The Magnaflow mufflers themselves seem to add a good tone for this particular motor, but with ONLY a cat-back, it just doesn't feel/sound like enough of an upgrade for the more hardcore "tuners" in our community, such as myself. :P

Each to his/her own but I can see little benefit to putting a Magnaflow on a 4 banger, especially with only one muffler! True, you will add a little more muscle sound but who the heck wants a Caddy that sounds like a rice burner..!! Kid stuff! I have had big American V8's most of my life including 3 ZR-1's and now a C6. The C6 runs a Magnaflow cat back, and while it produces a really nice muscle car sound [not at all kid like or cheap hot rod sounding] it does little for increasing performance. When I went with a Magnaflow type on 2 of my ZR-1's I did get increased 1/4 mile trap speeds by about 3 or 4 mph but they did little for the ET's. Magnaflow makes nice products, but why on a Cadillac!

Because the stock 2.0 sounds really bad. Not just quiet. I'm cool with quiet. But it's almost embarrassing to Rev that engine I think lol.

The only exhaust piece worth any performance improvement on a 4 cylinder turbo would be a downpipe.

Everything else is just for sound.

3 or 4 mph in the 1/4, I want some of those mufflers. That's quite a bit of gain just for mufflers? I race all the time and have never seen increases like that?

A hiflow cat after the downpipe would also help reduce backpressure.

I think it's kind of cool that it's not overly loud, if you can do a new video with it a bit broken in that would be great! In your opinion, compared to a 3.6L, is it louder or quieter?

Also, how audible is it in the car?

Yes, it was a complete 3" cat back system and the mufflers were Walkers! LT5's needed to get the exhaust out as you cranked the rpm towards 7,000! My best prior was 111-112 after the exhaust it was always 114-115mph.

As with most anything, "because you can", more importantly, because aftermarket anything will help get this car and brand some much needed visibilty.

This would be a major mistake! Borla on a Cadillac..!!! Kid stuff. Borla is too hot rod or rice burner sounding. Some guys put them on Corvettes and they make the car sound like an 18 year old's car! No sophistication at all. Try the more upscale after market producers like Corsa or Magnaflow, etc. Borla is cheap product and they sound like cheap. You may have a differing opinion but you have a $35k automobile, why make it sound like someones 1969 Mustang, or worse....!!!

I also disagree with modding "because you can". I say bull. You can take away from a cars appeal and most certainly its value by making foolish mods! Corvette guys do it all the time and when it comes time to sell, most end up reverting back to stock! And Corvettes lend themselves to modding.

IMHO magnaflow is best for american cars.

It's stainless steel and chrome, not classy or unclassy just metal, since the tone of the not classy bunch here seems to lean toward muscle and rice cars in the not classy column, it seems odd to me that cadillac chose them as an OEM partner along with Daimler, and Lexus.

That's what I was afraid of... I knew there was a 2.5L kit in the works.

I'm almost tempted to wait till the ATSV comes out and look at picking up a take-off exhaust and rear bumper and adding a resonator to have a quad tip exhaust - I prefer the look of 4 small tips to 2 large ones and that won't fit in the stock bumper.

$950 for a BORLA! Highway robbery and not worth a third of that. I know Caddy demands a premium but no Borla should cost anywhere near a grand! Plus, all there is is a muffler and tips. I have a complete catback Magnaflow system on my C6 that is all SS with 2 mufflers & rolled quad 4" highly polished tips. Now that setup is worth a grand!! Made a mistake years ago and put a Borla on a Camaro L98. It was crap then for like $135. !!!

not positive but i think the plastic piece is a new diffuser, which would make sense considering if this fits the 2.5 as well you'd need an extra opening, so not chump change, but i don't think unreasonable for a catback, muffler and chrome tips if lower body panel is included

See.. the regular 2.5 only has a single exhaust.

I would like to know if this is simply the dual tip exhaust from the 2.0T/3.6 or if it's infact a different muffler.

The fact that it includes the Fascia leads me to believe this is simply the 'upgrade' for the single tip 2.5.

Parts guy says, for base through luxury all engines '13 and '14 so one could deduce this is not the case or else why would this be an upgrade for the turbo and v6 too, but to your point it could be the performance/premium exhaust since those are not included in this upgrade

06-11-13, 05:37 PM
by the way guys, the muffler that is shown in the picture and all the links is just an upgrade to dual exhaust tips for the 2.5 engine. one easy way to tell is if u look at the picture posted by pissedoffwookiee, the muffler has one pipe going into it. the stock 2.0T has 2 seperate pipes going into the muffler and 2 coming out. so this isnt rly a performance upgrade. maybe for sound but i think its just cosmetics. wont fit on the 2.0T or the 3.6

Borla had used my 2.0T Sonata for their R&D prototype cat-back exhaust and it has had a bad howling/whistling sound at full-throttle since day 1.

They tried to deny it and they sent me replacement tips, but it's still there. Hell it's even apparent in the YouTube videos they have of my car, and I have several of my own as evidence.

I honestly won't buy Borla products ever again. While I was there I got a tour of their R&D facility in Port Hueneme, Cali... they simply use perforated piping inside of their pipes. Not that damn special, you guys.

For the money, I'd rather just have my local shop fab me up a nice 2.5" setup with WHATEVER brand of mufflers I choose.

Looks like a nice Exhaust. I have a Solstice GXP with a Magnaflow, K&N Drop in, and Trifecta Tune. On the Solstice is has a really nice Deep Throaty sound. I think the Magnaflow on the ATS 2.0T does sound a little quiet I think its because it does not eliminate the second cat. The Solsitce only has one primary cat (Downpipe). Get rid of that second cat for a more aggressive exhaust note and free up a little power at the same time.

I have this exhaust installed on my ATS and I will admit it is amazing. Very nice sound no drone, lighter than the stock system, easy install and high quality.

So... Both the secondary cat and the resonator are removed? I noticed the tips seem to be resonated. I wonder how much effect that has? If I get an exhaust, I'd want to keep the beautiful stock tips.

The Magnaflow kit seems to be well fitting and designed, but why would they bother to split to 2 pipes, only to come back into one muffler? It seems like added weight and cost to me. Why not slightly bigger single pipe to muffler with dual outlets? Fbody guys have been doing this for years
